iPhone 3G's 3rd Sensor? Another Proximity Sensor

There have been reports that the iPhone 3G was sporting a third sensor on the face of the phone. Well the details have come out and it's a...second proximity sensor! Yep, no front-facing camera, just another feature we already had.

I assume you are a little disappointed in the news, but for what it's worth, the second proximity sensor will provide better accuracy compared to the original iPhone's one proximity sensor get up. It's supposed to improve the iPhone's face proximity detection and well 2 is better than 1 right?

The sensors have also found a new home moving from above the speaker in the original iPhone to the left of the speaker in the iPhone 3G. Also, the three sensors create a J shape as opposed to the single straight line of the original iPhone.
